There are provided a nutritious supplemental composition for suppression against large intestinal cancer and its manufacturing method in which dietary fiber in a range of 15 wt % to 30 wt % in respect to a total amount of composition is contained in the dried koji fine powder including dead fungi of Aspergillus while keeping a capability of catalysis of groups of enzyme produced by Aspergillus.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a nutritious supplemental composition for suppression against onset of large intestinal cancer in which it shows a superior suppression against onset of large intestinal cancer.

[0003] In particular, in the present invention, rice bran is heated with steam, Aspergillus, Aspergillus oryzae strain, for example, is mixed with the rice bran, they are cultivated and ripened to make rice bran koji, Aspergillus is annihilated, and the enzyme groups produced by Aspergillus are changed into the dried koji fine powder of dried powder under a state in which a proper capability of catalysis of enzyme itself is not lost.

[0004] Either dietary fiber aiming at removal of mutagen or plant protein acting as nutritious element is contained in it and the present invention relates to the nutritious supplemental composition for suppression against onset of large intestinal cancer and its manufacturing method.

[0005] 2. Description of the Related Art

[0006] Cancer is totally defined as malignant tumor in general. As causes for oncogenesis, they are roughly classified into chemical oncogenesis with carcinogenic substance and viral oncogenesis.

[0007] As chemical oncogenesis substances, a tremendous number of carcinogen substances are applied. Also as to viral oncogenesis, it has been apparent that the number of types exceed 100 types or more. In addition, it has become apparent that a reason why cancer occurs consists in the fact that a combination among the chemical oncogenesis substances and genes owned by a specific person is related to it and more than 100 type of oncogenes have been reported.

[0008] In recent years, aberrant crypt foci (ACF) appearing in a rat at an initial dosing time of carcinogenic substances (azoxymethane=AOM, for example) has been noticed as precancerous lesion of large Intestinal, this lesion is acknowledged in its presence at a human, so that this is assumed to be one of the important indexes for prevention of onset of large intestinal cancer.

[0009] As mutagen changing a proper character of cell itself, there are present “direct mutagen” such as nitroso compound or antiseptic agent, for example, giving derangement directly to gene in the cell; and “indirect mutagen” activated in a human body by enzyme such as decomposition product of amino acid or protein found in scorched meat or fish or like, for example.

[0010] It is said that aberrant crypt foci generated by the “mutagen” is precancerous lesin of large intestinal and has a high possibility of becoming a large intestinal cancer in the future.

[0011] Experiment has shown it apparent that substance for suppression against this “aberrant crypt foci” can suppress approximately by 70% the large intestinal cancer which is onset by the “aberrant crypt foci”.

[0012] Further, in opposition to the carcinostatic chemotherapy, a viewpoint has been set in recent years to a direct breakage of cancer cell under application of function of biophylaxis of host through killer cells or immunocomplement cell or enforcement of biological function indirectly retracting cancer by reinforcing function of organism and a concept of applying biological response modifier (BRM) has been advocated in a medical field.

[0013] Along with this trend, a study about medicines or foods for activating an immune system has also been promoted and frequently shown that the foods derived from bacteria or mycete, for example, lactobacillus lactis, lactic acid coccus, cultivated basidiomycetes mycelioid (Aspergillus), fruit body of mushroom or the like have stimulus activation against the surface of leukocyte membrane.

[0014] As a representing example of this material, both production and discharging of cytokine (this is a general term of non-antibody protein such as lymphokines assisting action of cellular inmmune by stimulating either monocyte or macrophage or the like with groups of soluble substances discharged by sensitized limphocyte contacted with specific antigens. This may act as an intercellular regulation factor when an immune response occurs.) are applied through stimulation of immunity system with component (generally called as an LPS) constituted by ell walls of β-glucan contained in plant or gram-negative bacteria such as lactic acid bacteria or the like.

[0015] In addition, it is often said that some foods derived from plants or animals, for example, chlorella, Nemacystus decipiens and other sea weeds (sulfuric acid polysaccharide), green and yellow leaf vegetables (carotenoid and others), fruits or the like (polyphenols and the like), beans (soybean peptide), rice bran (arabinoxylan and others), nucleic acid (salmon DNA), crusts (chitin, chitosan), shells (zinc, selenium) and the like show a mechanism for adjusting metabolic activity in leukocyte cells. As its typical example, there is provided an activation of metabolism enzyme by sulfide contained in vegetables.

[0016] In turn, it has been made apparent academically that vegetables (spinach, field pea, burdock, yam, nettle tree mushroom, mushroom, ginkgo nut, corn, green peas, or the like) or fruits (orange, grape fruit, mandarin range, apple or the like) have superior actions and effects against suppression against production of mutagen in a human body, inactivation of mutagen, suppression against metabolism activation of mutagen, inactivation against mutagen of metabolism activation and suppression against fixation of mutation of gene or the like.

[0017] That is, a canceration cell shows a cytodieresis by transmitting a specific signal within the cell itself even if a certain signal about proliferation is not received due to irregular state in its receptor related to proliferation. In this case, it is known that pigment systems such as carotenoid or the like contained in vegetable juice and the like may improve irregular state of receptor of cell.

[0018] As effective constituents acting as anti-mutagen substances contained in these vegetables and the like, there are cited examples such as vitamins e.g. vitamin C, proline (a type of α-amino acid), thio proline, glutathione (having a reducing action), cysteine (α-amino acid containing sulfur atom, wherein —SH in its structure is important for bioactivity), compound of sulfur and hydrogen, and dietary fiber and the like.

[0019] Reduction in carbohydrate metabolism function as derangement of metabolism function concerning nourishment has a substantial meaning as an index for aging, wherein a peak age in which carbohydrate metabolism function of a human is about 65-year age while a high-aged trend is progressive, hypergasia in total function of nutritious metabolism including carbohydrate metabolism may product a lack in energy at each of the secretion organs, resulting in that it becomes a major cause in a bad condition in physical state to generate a series of syndrome.

[0020] As cancers were onset in Japanese people, tremendous number of people suffering from gastric cancer were found overwhelmingly, although in recent years in Japan, a number of people taking meat foods has been increased and the number of some people taking vegetable foods has been decreased to cause unbalanced foods to be eaten, resulting in that it is reported that a rate of onset of large intestinal cancer has been increased and country where people take much amount of fat shows a large number of mammary cancers. However, a rate of onset of mammary cancers in Japan also shows an increasing trend in number.

[0021] If it is assumed that a rate of death classified by statistical age for cancers in recent Japan is defined as a numerical value of 1 for age 24 or 25, the rate of death over age 40 exceeds by 9 times at once. This value increases by leaps and bounds like 29 times in fifties, 70 times in sixties and 152 times in seventies, respectively.

[0022] It is possible to say that this numerical value is proportional to a trend of reduction in immunity function accompanied by a reduction in metabolism function caused by the aforesaid aging.

[0023] It is defined such that taking much amount of meat causes either Clostridium perfringens or escherichiacoli colibacillus to become predominant within intestine and further promote proliferation of toxbacteria, resulting in that blood derangement is produced by derangement of tissue or gangrene with gas derived from toxbacteria and large intestinal cancer becomes onset.

[0024] In addition, scorching of protein as found in meat or hamburger under application of heat causes carcinogen substances such as Trp-p-1, Trp-p-2 or the like to be generated, wherein the carcinogen substances may promote not only large intestinal cancer but also mammary cancer and prostatic cancer.

[0025] However, taking a large amount of vegetables or dietary fibers shows a serious question in view of meal configuration as well as digestive capability.

SUMMARY OF THE INVENTION

[0026] The present inventor has performed a wider and deeper study to develop a nutritious supplemental food that everybody can take in an easy manner, showing a high food value and a superior absorbability in view of acknowledgement in study that suppression of aging of a human body is attained by intake of balanced nutrition and activation of metabolism through improved environment of tissue cell in organism, keeping a healthy condition itself results in activation of immune function to prevent and suppress various kinds of sicknesses.

[0027] As a result, dietary fiber is included in cereal constituent containing not devitalized enzyme with rice bran koji being applied as major material to generate constituent. This constituent has a well-balanced nutrition, contributes to improvement of environment of cell to activate cell and further promote activation of a metabolism function and an immune function. Additionally, this constituent may suppress active oxygen in a human body becoming one of mutagen and further suppress onset of aberrant crypt foci.

[0028] Further, the present inventor has searched the fact that 6-phytase produced by Aspergillus in the constituent of the present invention decomposes phytin in a plant (calcium salt and magnesium salt of myoinosithexaphosphate), facilitates it to be absorbed, so that it is not necessary to take a large amount of vegetables or dietary fiber, and then the present inventor has invented this invention.

[0029] In the present invention, following technical means have been set in order to resolve the aforesaid problems.

[0030] That is, rice bran is steamed, Aspergillus strain colony is cultivated and ripened to attain rice bran koji, Aspergillus is diminished to attain dried substances including dead fungi, enzyme groups produced by the Aspergillus strain colony are contained in the dried koji fine powder under a state in which catalysis of the enzyme itself is not lost. This constituent includes either dietary fiber or plant protein.

[0031] In this case, cereal or the like such as unpolished rice is cultivated by Aspergillus together with rice bran and lactic acid bacteria can be cultivated by Aspergillus.

[0032] A practical configuration of the present invention is as follows.

[0033] (1) A nutritious supplemental composition for suppression against onset of large intestinal cancer, wherein a capability of catalysis of enzyme groups produced by Aspergillus is held as it is and dietary fiber in a range of 15 wt % to 30 wt % in respect to a total amount of composition is contained in dried koji fine powder including dead fungi of Aspergillus.

[0034] (2) A nutritious supplemental composition for suppression against onset of large intestinal cancer, wherein a capability of catalysis of enzyme groups produced by Aspergillus is held as it is and plant protein in a range of 15 wt % to 30 wt % in respect to a total amount of composition is contained in dried koji fine powder including dead fungi of Aspergillus.

[0035] (3) A nutritious supplemental composition for suppression against onset of large intestinal cancer, wherein a capability of catalysis of enzyme groups produced by Aspergillus is held as it is, dietary fiber in a range of 15 wt % to 30 wt % in respect to a total amount of composition and plant protein in a range of 15 wt % to 30 wt % in respect to a total amount of composition are contained in dried koji fine powder including dead fungi of Aspergillus.

[0036] (4) A nutritious supplemental composition for suppression against onset of large intestinal cancer according to any one of (1) to (3), wherein dead fungi of lactic acid bacteria are also included in said dried koji fine powder.

[0037] (5) A nutritious supplemental composition for suppression against onset of large intestinal cancer according to any one of (1) to (4), wherein said dried koji is rice bran koji.

[0038] (6) A nutritious supplemental composition for suppression against onset of large intestinal cancer according to (5), wherein either a single or mixed crop koji selected from rice bran koji, barley koji, corn koji, bean koji, and barley bran koji are contained in said rice bran koji in a range of 5 wt % to 30 wt %.

[0039] (7) A method for manufacturing a nutritious supplemental composition for suppression against onset of large intestinal cancer, wherein after Aspergillus is cultivated and ripened at steamed rice bran, a temperature of ripened product is kept at 44° C. to 46° C., the ripened product (koji) is formed into dried rice bran koji containing dead fungi of Aspergillus while keeping a capability of catalysis of enzyme groups produced by Aspergillus and further changed into fine powder and dietary fiber powder is uniformly mixed with the dried rice bran koji fine powder under a state in which there is no difference in their humidity.

[0040] (8) A method for manufacturing a nutritious supplemental composition for suppression against onset of large intestinal cancer, wherein after Aspergillus is cultivated and ripened at steamed rice bran, a temperature of ripened product is kept at 44° C. to 46° C., the ripened product (koji) is formed into dried rice bran koji fine powder containing dead fungi of Aspergillus while keeping a capability of catalysis of enzyme groups produced by Aspergillus and further formed into fine powder, and the plant protein powder is uniformly mixed with said dried rice bran koji powder under a state in which there is no difference in their humidity.

[0041] (9) A method for manufacturing a nutritious supplemental composition for suppression against onset of large intestinal cancer according to any one of (7), (8), wherein after Aspergillus and lactic acid bacteria are cultivated and ripened, the ripened product is formed into dried rice bran koji containing dead fungi of Aspergillus and lactic acid bacteria while keeping a capability of catalysis of enzyme groups produced by Aspergillus.

[0042] Unpolished rice surface contains the rind, seed coat and powder layers occupying by about 5% and embryo bud by about 3% of entire unpolished rice, and these portions peeled off by rice cleaning operation are defined as rice bran. In addition to glycoprotein, minerals or vitamins, the embryo bud and seed coat of rice bran contain phytin acid (myoinositheraphosphat, its abbreviated symbol IP₆) in the form of phytin (calcium salt, magnesium salt of phytin acid), myoinositol (this is known as a part in which phosphorus acid is removed from phytic acid, a part of vitamin B complex required for growth of yeast or growth of mouse, and as carcinostatic substance), arabinoxylan, ferulic acid (having functions to diminish radical of anticoagulate, diminish active oxygen and prevent onset of large intestinal cancer), amino butyric acid (α-amino acid of which small amount is present in protein, this is related to respiration of brain tissue), polysaccharide, antioxidant, and unsaturated fatty acid or the like.

[0043] Almost of natural proteins contained in embryo bud are glycoprotein coupled to sugar. Although a physiological meaning of sugar chain of glycoprotein is not yet explicated well, functions of sugar chain already known are deeply related to cognizance of inter-cells by difference in shape of sugar chains, and migration in organism and proteinmetabolism of cell or the like, and it is considered that inflammation caused by mutagenesis substances such as active oxygen or bacteria and the like may induce variation in sugar chain binding as well as cognizance disability of inter-cell, resulting in that either immunodeficiency or decompensation is produced.

[0044] Lactic acid bacteria decomposes sugar substances contained in rice bran. A certain academic report indicates that lactic acid bacteria die out with heat of 41° C. or higher and the dead fungi have some effects against constituents composing the cell that various kinds of immunologic reactions in organism are activated, and a high antitumor action or infection protection is attained.

[0045] There is another academic report that a single dosage of lactic acid bacteria in addition to dietary fiber has an effect of scavenger (cleaning action) in which the number of cancer cells showing liver metastasis is restricted.

[0046] As the constituent in the present invention, dried powder such as plant leaves, stalks, seeds (beans, seeds) having much amount of fibrous substances can be applied as dietary fibers.

[0047] As major dietary fibers constituted by protein, there are provided cellulose acting as major constituents of a cell wall of plant (polysaccharide that is a basic substance of plant fiber occupying by about ⅓ of the plant), hemicellulose (this is polysaccharide of plant cell wall closely related to xylan, manna, galactans and others), lignin (aromatic polymer substance present in ligneous cell wall), pectin (gelatin-like acid polysaccharide present as inter-cell substance of plant), alginic acid (polysaccharide of phlegm forming a cell membrane of sea weeds) and glucomannan (polysaccharide having, as its major constituent, mannose) or the like.

[0048] It has been made apparent that polysaccharide (macromolecular sugar chain) activates leukocyte, stimulates a cytokine network, causes hormone system to act and further activates immune function.

[0049] These dietary fibers are classified as water-soluble dietary fiber and insoluble dietary fiber. The water-soluble dietary fiber has a function to reduce blood serum cholesterol and a function to suppress increasing of blood sugar value in postprandial state.

[0050] Insoluble dietary fiber has a function to adsorb either carcinogen substances or carcinogen promoting substances in intestine and discharge them out of a human body. It is also reported that pectin of water-soluble dietary fiber has an effect to suppress large intestinal cancer. In addition, a large amount of phytin acid and myoinositol contained in a plant as a form of phytin are known as carcinostatic substance.

[0051] It is acknowledged by an animal model induced with large intestinal cancer that all phytic acid, myoinositol and inositol compound are superior in prevention of onset of abberant crypt foci and an experiment with a nude mouse dosed with these combined substances has reported that the mouse shows an effect of suppression of onsets of large intestinal cancer, fibrosarcoma and mammary cancer or the like.

[0052] For a human body, dosing of 1 to 2 g per day of phytic acid and myoinositol shows an effect of prevention of large intestinal cancer and for a person having a high risk of onset of large intestinal cancer, a twice amount of this volume is sufficient for prevention of it.

[0053] An academic report has shown that this phytic acid is not only a carcinostatic substance but also has prevention of arteriolosclerosis, prevention of senescence and anti-oxidation action.

[0054] In accordance with this academic report, an organism has enzyme called as glutathione-S-transferase (GST) having a function to detoxicate chemical substances, i.e. mutagen coming from an external environment into a human body and inactivate it, wherein when the experiment rat is dosed with phytic acid (2% of feed), GST activation characteristic for inactivating chemical substances containing these carcinogen substances in a liver of rat increases with a significant difference to cause mutagen substances to be decreased.

[0055] There is provided an academic report that phytic acid itself has not only an effect of prevention against large intestinal cancer, but also has an effect that an effective effect of suppression against large intestinal cancer under combination with green tea (concentration of 2%) can be expected, and an effect of suppression against large intestinal cancer can be improved more under combination with myoinositol having phosphoric acid removed from phytic acid.

[0056] As for a rat, this phytic acid is decomposed by 6-phytase derived from small intestine mucosa (enzyme processed with hydrolysis to remove 6-phosphoric acid) and absorbed, although as for a human body, activation of 6-phytase derived from small intestine mucosa is quite low as compared with that of rat, so that it can be scarcely absorbed unless 6-phytase derived from meal is present even if this 6-phytase is taken. In addition, it is assumed that phytic acid is hardly absorbed under a state in which it is combined with protein.

[0057] In view of this meaning, protein decomposing enzyme in the constituent of the present invention decomposes protein, 6-phytase produced by Aspergillus performs a hydrolysis operation against phytin and phytic acid to absorb phytic acid (IP₆), although it is decomposed into IP₅, IP₄, IP₃ and myoinositol and the like, and it may become easily absorbed. In addition, either magnesium or calcium or the like is separated from phosphoric acid group and becomes easily absorbed.

[0058] With such an arrangement as above, even if a large amount of dietary fibers containing phytin are not taken, it is possible to attain a substantial effect of phytic acid as well as a substantial effect of myoinositol. Phytic acid reaches various kinds of organ in an organism in about one hour after taking it and has an immediate effect realizing its action.

[0059] The constituent of the present invention containing much amount of these substances descried above is well balanced in its nutrition and contains much amount of biophylaxis activating substances. When a person takes about 20 g of this constituent every day as nutritious supplemental food in a continuous manner, his or her regular food together with this supplemental food under their synergism enables environment of cells to be improved. As a result, energy is given to the cell, a metabolism function and immune function or the like can be improved to enable keeping of a healthy condition to be carried out.

[0060] In addition, substances for suppressing “mutagen” abundantly contained in this composition may eliminate “mutagen”, restrict onset of precancerous lesion of large intestinal cancer, resulting in that it realizes a superior effect in suppression of large intestinal cancer.

[0061] In particular, when 6-phytase generated by Aspergillus is taken, it performs a hydrolysis work for phytic acid in a form of phytin to cause it to be absorbed well, so that it is possible to attain an efficient pharmacodynamic action of myoinositol as well as phytic acid contained in the composition of the present invention even if a large amount of vegetables or dietary fibers are not taken.

[0062] A “product temperature” herein defined is meant by a temperature of raw material where heat is generated at a culture bed through Aspergillus cultivation. As “rice bran koji”, it also contains koji in which crop koji is mixed at a rate of 30% or less.

[0063] The present invention has the following superior effects.

[0064] (1) If a large amount of the composition of the present invention described in claim 1 are taken into a body, each of the enzymes of which large amount are contained may perform a catalysis action within the body. Protein is decomposed into low molecular moles to enable amino acid to be supplied and then protein may act organically to compose amino acid for cells of organism. In addition, one part of the dietary fiber is decomposed with enzyme, the other part of the dietary fiber is non-soluble, goes to the colon, adsorbs carcinogen, discharges it out of the body, stimulates the intestine wall to eliminate constipation.

[0065] The dead fungi are decomposed with enzyme in the body, absorbed into the body so as to activate immunologic reaction.

[0066] 6-phytase generated by Aspergillus in the composition of the present invention performs a hydrolysis action against phytic acid in a form of phytin to cause it to be easily absorbed.

[0067] Accordingly, even if a large amount of vegetables or dietary fiber is not taken, either phytic acid or myoinositol can be efficiently absorbed, the composition may reach various kinds of organs in about one hour after a person takes this composition and it may attain an accumulative effect capable of realizing its action in an immediate effective manner.

[0068] Vitamins, minerals and other nutritious elements abundantly contained in the composition of the present invention become energy of cells in the organism and provide some effects that the environment of cells is improved, metabolism function as well as immune function properly included in the cells are improved, these accumulative effect may prevent aging to keep healthy condition of a human body and at the same time the composition having action to suppress onset of large intestinal cancer can be easily attained.

[0069] (2) The composition of the present invention described in claim 2 contains plant protein in dried koji powder keeping a capability of catalysis of enzyme proper, so that in addition to the effects described in the above item (1), it has some effects that even if a person does not supply protein additionally, mere taking of the present composition enables the person to take sufficient plant protein, the protein is supplied to the cell as amino acid and acts against sugar chain of the cell and the composition of amino acid in an organic manner. With such an arrangement as above, the present invention has some effects capable of contributing to recover a healthy condition and keep it as well and attaining composition for suppressing onset of large intestinal cancer through its accumulative action.

[0070] (3) The composition of the present invention described in claim 3 contains dietary fibers and plant protein, so that it has an effect combined with some effects described in the above items (1) and (2).

[0071] (4) The composition described in claim 4 is composition having less amount of sugar by lactic acid bacteria and dead fungi of lactic acid bacteria shows some effects of attaining stimulation of immune system with the component of cell wall of lactic acid bacteria, production of cytokine and its discharging as well.

[0072] (5) The invention described in claim 5 has an effect that nutrition at the embryo bud of unpolished rice can be utilized concentrically.

[0073] (6) The composition described in claim 6 contains either a single or mixed crop koji selected from rice koji, barley koji, corn koji, bean koji, and barley bran koji, so that they may supplement each of poor substances in the food and provide an effect preferably accumulative one.

[0074] (7) The manufacturing method described in claim 7 can manufacture uniform rice bran koji. In addition, dried rice bran koji fine powder can be provided in such a way that the groups of enzyme produced by Aspergillus may not lose a capability of catalysis of enzyme proper. When the dietary fiber fine powder is mixed with the rice bran koji fine powder, both of them are mixed to each other under a state in which no difference occurs in temperature and humidity, thereby they can be mixed in a uniform density, resulting in that the mixed composition has an effect that the composition superior for suppression against onset of large intestinal cancer can be easily manufactured.

[0075] (8) The manufacturing method described in claim 8 can manufacture uniform rice bran koji. In addition, dried rice bran koji fine powder can be provided in such a way that the groups of enzyme produced by Aspergillus may not lose a capability of catalysis of enzyme proper. When the plant protein fine powder is mixed with the rice bran koji fine powder, both of them can be mixed to each other under a state in which no difference occurs in temperature and humidity, thereby they can be mixed in a uniform density, resulting in that the mixed composition has an effect that the composition superior for suppression against onset of large intestinal cancer can be easily manufactured.

[0076] (9) The manufacturing method described in claim 9 has an effect that dried rice bran koji containing less amount of sugar by decomposing sugar produced by lactic acid bacteria.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0077] Preferred embodiments of the present invention will be described as follows.

[0078] Method Preferred Embodiment 1

[0079] Selected rice bran is put into a water applying machine, water by about 25 wt % to 30 wt % in regard to raw material is added, water is sufficiently absorbed into the selected rice bran to cause this bran to be bulged. The bulged bran is put into a steamer, calcareous powder (baked oyster shell powder=grain size #250 mesh to #400 mesh) is added by about 0.5 wt % to 1 wt %, respectively, and these materials are steamed with steam of 100° C. to 120° C. for about 50 to 60 minutes while their moisture being checked. When crops such as unpolished rice are applied, they are steamed together with rice bran.

[0080] Rice bran completely steamed up is released to cool down to about 37° C. to 40° C. and Aspergillus strain colony, Aspergillus oryzae strain, for example, is added by about 0.1 wt % and they are well mixed to each other.

[0081] In this case, it is possible to use Aspergillus selected from other kojis (A. Kawachii, A. Awamori, A. Usami). In addition, as needed, a small amount of lactic acid bacteria (of about 2.5×10 pieces/g to 3.0×102 pieces/g) is added. If required, the same amounts of yeast and lactic acid bacteria as those of Aspergillus can be added.

[0082] Aspergillus strain colony vigorously secretes decomposing enzymes such as amylase, protease and lipase or the like to decompose sugar and protein contained in rice bran into low molecules. The lactic acid bacteria decomposes sugar. Temperature suitable for cultivation of Aspergillus and lactic acid bacteria is 35° C. to 37° C. and humidity is 85% RH to 90% RH, and activity in bacteria is stopped under a humidity of 70% RH or less. Raw material having Aspergillus and lactic acid bacteria is cultivated for 32 to 36 hours while temperature and humidity are being adjusted in a stepwise manner in a range of room temperature of 35° C. to 37° C. and in a range of humidity of 50% RH and 90% RH.

[0083] The rice bran at the culture bed are not closely contacted with each other by calcareous powder uniformly adhered to the surfaces of the rice bran to form a proper degree of aeration clearance and Aspergillus strain colony is cultivated under a state where airflow is well kept in an average manner.

[0084] At the culture bed, its temperature is increased automatically from a temperature of 25° C. to 38° C. gradually under application of cultivation heat of the Aspergillus strain colony. This state is kept for a minimum time of 8 hours. When a temperature of product (a temperature of raw material in the cultivation bed) becomes 40° C. to 41° C., the culture bed is agitated to cause the temperature of product to be forcedly decreased in such a way that an activity of species bacteria is not made dull. At this time, the temperature of product is decreased down to about 32° C. and increased again up to a certain temperature.

[0085] A growing period in which ripening of Aspergillus strain colony is promoted is controlled at a room temperature of 31° C. to 36° C. in such a way that the temperature of the product does not exceed 40° C., and when the temperature of the product becomes 40° C. to 42° C. after 6 hours, the culture bed is agitated to decrease the temperature of the product. After this operation, both temperature and humidity are adjusted in such a way that the temperature of the product may become a range of 39° C. to 40° C. and then the material is cultured for 11 hours to 12 hours. Since the Aspergillus strain colony is aerobe, the agitation of culture bed is carried out for three to four times for every specified time (8 hours) during this period to supply oxygen, a color check and an odor check are performed, and further a ripening and a degree of dry are adjusted through agitation of the culture bed.

[0086] At a period of standstill in which growing of the Aspergillus strain colony is stopped, the humidity is adjusted to 70% RH or less where activity of Aspergillus is made dull and the room temperature is increased up to 36° C. to 37° C. The temperature of the product is adjusted to a range of 39.5° C. to 40° C., the product is ripened for 6 hours to attain rice bran koji. At this time, a value of pH at the culture bed is kept at 6 to 7.

[0087] After this operation, the rice bran koji at the culture bed is dried for 9 hours at a room temperature of 46° C. to 53° C. as it is. The temperature of the product is restricted in a range of 44° C. to 46° C., activities of Aspergillus and lactic acid bacteria are completely stopped and die out. Upon completion of drying operation, the product becomes a dried material with a component moisture being less than 4%, 2.5% to 3.6%, respectively. In this connection, the component moisture of normal rice bran is 13 to 14%.

[0088] This dried rice bran koji is applied to a screen to remove block rigid product with a size of 5 mm or more, applied to a pulverizer to attain dried koji fine powder while a degree of fine powder being checked.

[0089] As applied unpolished rice, three kinds of rice of different producing districts were mixed to each other. As calcareous powder, baked oyster shell powder was selected. However, bone powder, calcium lactate, crab shells or the like can be applied and so the type of raw material is not limited.

[0090] In the case of the aforesaid method, lactic acid bacteria added in addition to Aspergillus is anaerobic, so that sugar is decomposed and decreased in the layer where less amount of air flow is produced at the raw material in the culture bed. This lactic acid bacteria also dies out with heat at the time of drying stage.

[0091] Method Preferred Embodiment 2

[0092] Either single crop or mixed crops selected from unpolished rice, barley, corn, soybean and barley bran are mixed with the rice bran in a range of 5 to 30 wt %, steamed and the cultivation with Aspergillus and lactic acid bacteria is carried out in the same manner as that of the preferred embodiment 1. A drying step after ripening is also the same as that of the preferred embodiment 1. These crops can be cultivated with Aspergillus separate from rice bran and mixed with it.

[0093] Then, non-heated dried dietary fiber fine powder (moisture content of 2.5% to 3.6%) of 2 wt % to 30 wt % of a total amount of composition is added to and mixed with the dried koji fine powder manufactured in this way so that there occurs no difference in humidity between the dried koji fine powder and the non-heated dried dietary fiber fine powder. That is, they are fine powder, so that if there is a substantial difference in humidity between these materials, a certain block may easily be formed when they are mixed to each other and a trouble may occur in a uniform mixing.

[0094] As the dietary fiber added to the dried koji fine powder, it is possible to cite, as an example for it, fine powder of all dried mushrooms (shiitake, maitake, eringi, gano-derma lucidum and others), thumbmurray (G. pentaphyllum), kidney bean, field pea, ashida, mugwort, spinach, Brassica Rapa var. pervidis, tea leaf, burdock, bamboo shoot, carrot, onion, green pepper, konjak, sweet potato, ginger, seed of vegetable (soy bean), rice bran, wheat bran powder, soy shell powder, sea weeds, fruits, persimmon leaf, bamboo leaf and other materials. Since these materials are powder of whole dried substances, other several nutritious constituents in addition to fibers are abundantly contained.

[0095] The dietary fibers of these vegetables and fruits show an important relation for recovering metabolic disease, adsorb mutagenesis substances in a large intestinal and eliminate them, so that their physiologic functions have been noticed. In addition, the dietary fibers stimulate the wall of intestine to promote hyper peristalsis and eliminate constipation.

[0096] As a drying step for vegetables and fruits, it is preferable to apply a non-heated frozen low temperature drying. The dietary fiber fine powder having vegetables dried can be mixed in a range of 2 wt % to 30 wt % in respect to a total amount of constituent. Further, the dietary fibers extracted from these vegetables can be applied.

[0097] Mushrooms (Maitake, gano-derma lucidum, Agarisk, shiitake [Lentinus edodes] and others) contain much amount of constituents suppressing mutagenesis substances, such as fibrous constituents, phytic acid in a form of phytin, β-glucan or the like. In particular, it has already been made clear that β-glucan breaks tumor cell by activating immunocomplement cell in organism, resulting in that retrocession of cancer is attained. It is also reported that an experiment on prostatic cancer cell of a human body acknowledged that β-D-glucan induces a self-destruction inducing action.

[0098] Gingers contain protein decomposing enzyme and have an anti-bacteria action.

[0099] Seaweeds contain much amount of fibrous substances and also much amount of iodine promoting activation of hormone of hypophysis cerebri. A requirement of iodine per day for an adult person is set to 300 to 400 μg.

[0100] In addition, it is also possible to mix non-heated plant protein of 5 wt % to 30 wt % in respect to a total amount of composition with dried koji fine powder.

[0101] As the plant protein, it is possible to cite soy bean powder, soy bean protein, Spirulina and corn powder or the like. These substances supply non-heated protein and decompose enzyme in a human body to absorb amino acid.

[0102] Spirulina described above is a blue-green algae well grown in salt water, contains fibrous substance and chlorophyll and 60% of its entire volume is protein having stable amino acid.

[0104] Excipient material to be described later is added to single dried koji fine powder and mixed fine powder, they are formed into particles with a grain size of 1.2 mm to 1.3 mm by a granulating machine, packaged into a bag with weight of 3.5 g, 5 g and the like of one package by a packaging machine after drying operation, or not formed into granule, but into tablet by a tablet forming machine.

[0105] Although as the aforesaid excipient material, the raw material is not limited to this, the raw materials to be described later are optionally selected under a range of mixing, they are blended before forming particles (forming tablet), for example, to make particles or form tablets. Glucose  4 wt % to 12 wt % Lactose 12 wt % to 20 wt % Plant oil and fat  2 wt % to 6 wt %

[0106] A result of accumulative analysis of major compositions per 100 g of composition (rice bran koji by 65%, rice koji by 10%, soy bean protein by 20% and shiitake [Lentinus edodes] powder by 5%) manufactured in this way is as follows. Number of lactic acid bacteria 248,000 pieces/g to 253,000 pieces/g Titer of amilase 3200 U/g to 3400 U/g Titer of neutric protease 366 U/g to 383 U/g Titer of lipase 524 U/g to 536 U/g Saccharide 18.2 g to 18.5 g Protein (including amino acid) 22.4 g to 24.8 g Dietary fiber 18.5 g to 19.3 g Phytic acid 3.86 to 4.23 g Moisture 2.6 g to 3.4 g Energy 426 to 445 Kcal

[0107] Since the dried vegetables contain fiber by 70% or more, it is possible to increase an amount of inclusion of dietary fiber in the composition by 20% to 40% in reference to a blending amount. With such an increased amount of fiber, an amount of phytic acid can also be increased.

[0108] It is possible to increase an amount of inclusion of protein in the composition of the present invention in proportion to an added amount of the plant protein. Each of the aforesaid blending amounts is not limited to the indicated values.

[0109] The present inventor performed a short term experiment under application of rats for checking prevention of oncogenesis and suppression of onset with anti-mutagenesis substances, in particular, precancerous lesion of large intestinal cancer being applied as index of the composition of the present invention.

[0110] In the instant example, the present inventor performed study about prevention of oncogenesis of large intestinal cancer under application of composition of the present invention by target azoxymethane=AOM acting as carcinogens with an aberrant crypt foci induced at a rat large intestinal being applied as an index. As the composition of the present invention, substances of rice bran koji by 65%, rice koji by 10%, soy bean protein by 20% and gano-derma lucidum fine powder by 5 wt % were used.

[0111] (1) Method of Experiment

[0112] Male rats F344 with 5-week age in five groups were used and azoxymethane by 15 mg/kg was dosed subcutaneously at each of 12 rats of one group to four groups for one week and for two weeks after starting the experiment.

[0113] As for second to fourth groups, the composition of the present invention was mixed with a fundamental meal at a concentration of each of 1.25%, 2.5% and 5% and dosed in feed for each of experimental periods (five weeks).

[0114] As for the fifth group (four rats), no azoxymethane was applied, but only the composition of the present invention was mixed by 5% and fed to the rats.

[0115] Upon completion of the experiment, the rats were killed and their colons were fixed in formalin, thereafter they were dyed with methylene blue and a quantitative observation of aberrant crypt foci was carried out.

[0116] (2) Result of Experiment

[0117] In each of the groups, no significance difference was found in their average weight. Aberrant crypt foci of colon was acknowledged only at first to fourth groups. Each of average aberrant crypt foci for large intestinals in the first to fourth groups was First group: 139.5 ± 27.7 Second group: 122.6 ± 27.7 Third group:  99.0 ± 24.1 Fourth group:  79.0 ± 18.4

[0118] and each of the number of aberrant crypt foci of the third and fourth groups was significantly low (P<0.01) as compared with that of the first group.

[0119] In the case that they were classified in reference to the number of foci constituting the aberrant crypt foci, the value was low for one foci (P<0.05 or P<0.01) in any of the second to fourth groups as compared with the first group, the value was low for two foci (P<0.05 or P<0.01) in any of the third and fourth groups as compared with the first group, and the value was low (P<0.05) in more than four foci as compared with that of first group.

[0120] (3) Consideration

[0121] Study of this experiment has made it clear that dosing of the composition of the present invention may suppress onset of aberrant crypt foci induced at a rat colon. It is estimated that this effect of suppression of onset of aberrant crypt foci causes the composition of the present invention to have the prevention of large intestinal cancer of a human body.

[0122] Next, the present inventor performed experiment for a long period of time for the prevention of oncognesis under application of the composition of the present invention in the model of oncognesis of rat large intestinal cancer induced by carcinogens, i.e. azoxymethane=AOM for the large intestinal cancer.

[0123] (1) Method of Experiment

[0124] Male rats F344 of five-week age were classified into 7 groups with one group being constituted by 30 rats, sixth group and seventh group were excluded, and azoxymethane=AOM of 15 mg/kg was dosed subcutaneously by a total of three times once in every week from the first week to the third week after starting the experiment.

[0125] First group was fed with basic food for an experimental period. Each of the second group and the third group was fed with mixed substances of 5% and 2.5% of the composition of the present invention, respectively, for five weeks after starting the experiment, and subsequently, they were fed with the basic food.

[0126] The fourth group and the fifth group were fed with the basic food up to the fifth week, each of 5% and 2.5% of the composition of the present invention was mixed with the basic food and fed.

[0127] The sixth group and the seventh group were not fed with azoxymethane=AOM and only 5% of the composition of the present invention and the basic food were fed to them during the period of experiment.

[0128] After feeding for 40 weeks, all the rats were killed and a rate of onset and the number of onset of the tumor at the colon were compared.

[0129] (2) Result of Experiment

[0130] At the time of killing the rats, an average weight in each of the groups showed a slight decreasing trend in the group applied with azoxymethane as compared with that of non-processed group (the seventh group). Further, in the groups (the fourth, fifth and sixth groups) where the composition of the present invention has been dosed for a long period of time, a significant difference was not found in a weight ratio of liver and kidney of each of the groups.

[0131] Examination with the naked eye showed that the large intestinal tumor was found only in the first to fifth groups.

[0132] An incidence having a tumor in the first to fifth groups was; First group: 51.9% (14/27) Second group: 55.6% (15/27) Third group: 47.8% (11/23) Fourth group: 18.5% (5/27) Fifth group: 34.6% (9/26) and

[0133] it was confirmed that a trend of suppression against onset of tumor in the fourth and fifth groups occurred in response to concentration as compared with that of the first group, and the fourth group showed a decrease with a significant difference (P<0.05).

[0134] The number of onset of average tumor (multiplicity) per one rat in each of the groups was; First group: 0.77 ± 0.89 Second group: 0.70 ± 0.91 Third group: 0.68 ± 0.83 Fourth group: 0.18 ± 0.39 Fifth group: 0.42 ± 0.58 and

[0135] the fourth group showed a significant decrease as compared with that of the first group (P<0.01).

[0136] (3) Consideration

[0137] In the case of model of oncogenesis of large intestinal cancer in a rat induced by azoxymethane, the composition of the present invention did not show the effect of suppression in the groups (the second and third groups) fed with it at an initiation phase, although in the groups (the fourth and fifth groups) where the composition of the present invention was fed at a promotion phase, it showed an effect of suppression in response to a concentration and further an apparent suppression effect was found in the group (the fourth group) fed with 5% of the composition of the present invention.

[0138] As described above, the composition of the present invention is assumed to be promising as the suppression substance against onset of the large intestinal cancer in a human body. An amount of composition of the present invention which is efficient after a person takes it is about 14 g to 28 g per day and as the nutritious supplemental food taken for the sake of keeping health, about 14 g of it is satisfactory. As a standard value, 21 g per day is preferable.

[0139] An amount of inclusion of phytic acid in the test substance described above in this 21 g is 0.84 g to 0.93 g. Accordingly, increasing of an amount of addition of dietary fiber enables an amount of inclusion of phytic acid also to be increased.

[0140] To the contrary, as a result of performing the experiment for 29 weeks by dosing bran containing much amount of inclusion of phytic acid and a single phytic acid of the same amount as that contained in the bran to the model of onset of oncogenesis of large intestinal cancer induced by azoxymethane under the same condition, the group dosed with phytic acid was acknowledged to have a significant difference (a cancer onset frequency of 52.6%), although the group dosed with bran was not acknowledged to have a significant difference (a cancer onset frequency of 70%).

[0141] In view of this fact described above, it was acknowledged that even if a large amount of plant containing much amount of phytic acid was taken, an effect of suppression against onset of large intestinal cancer corresponding to an amount could not be expected.

[0142] An effect of herb medicine does not consist in an immediate effect, but improve a disease while recovering a health of human body. The composition of the present invention also contains much amount of nutritious elements as well as much amount of carsinostatic substances, and in particular, the fact that it contains decomposing enzyme for phytic acid provides a superior effect over suppression of onset against large intestinal cancer, resulting in that it may provide nutrition for improving environment of tissue cell and energy as well as improving a metabolism function and immune function and it has an effect acting as a herb medicine as well.

[0143] Further, the present invention is not limited to the aforesaid example of form, but both selection of raw materials such as dietary fiber and plant protein or the like and their blending rate can be optionally set on a case-by-case base.
